RESUMEN

Tick infestation is a major public and animal health concern causing significant financial losses, especially in tropical and subtropical regions of the world. This study aimed at investigating the epidemiologic profile of ticks infesting cattle and molecular identification of R. microplus in the centrally ignored part of Khyber Pakhtunkhwa, Pakistan. A total of 600 cattle from 20 farms were examined for the tick infestation, among them 358 (59.7%) cattle were infested with ticks. A total of 2118 nymph, larvae and adult tick stages were collected and morphologically identified followed by molecular confirmation of Rhipicephalus microplus. Host-based demographic and ecological parameter analysis revealed significantly higher tick infestation in adult, female, exotic, freely grazing, and with irregular/no acaricides treated cattle. The univariate logistic analysis showed that host age, gender, breed, acaricides use, and feeding method were significantly (P < 0.05) associated, whereas multivariate analysis revealed only host breed and feeding method were potential risk factors (P < 0.05) for tick infestation. Microscopy-based examination identified four different species of ticks including R. microplus (44.5%), Hyalomma anatolicum (38.5%), and Hyalomma marginatum (10.5%) and Hyalomma excavatum (6.5%). Tick infestation pattern showed that 55.9% of cattle was found co-infested with R. microplus and H. anatolicum followed by R. microplus and H. anatolicum and H. marginatum (29.3%) then R. microplus, H. anatolicum, H. marginatum, and H. excavatum (11.2%). Sequencing of the second internal transcribed spacer (ITS2-) and 16S rRNA gene fragments also confirmed the molecular identification of Rhipicephalus microplus. Phylogenetic analysis of ITS-2 revealed all sequences clustered in single clade of the R. microplus while the 16S rRNA nucleotide sequences showed that R. microplus in this study was clustered together in clade A along with other isolates from Pakistan, China, and India. The high tick infestation suggests the need for designing strategic and integrated control measures for ticks in order to ensure good health of domestic animals in this region of Pakistan.

RESUMEN

The current study assessed the ameliorative effect of Trigonella foenum graceum extract against copper oxide nanoparticles (CuO-NPs) induced toxicity in Oreochromis mossambicus. For this purpose 100 healthy fish weighing 20±2.34g were randomly divided into five different groups in duplicates and designated as control (C) no treatment, positive control (G*) treated with 0.12mg/L of CuO-NPs, experimental co-treated groups G1, G2 and G3 were treated with Trigonella foenum-graecum extract @ 18, 26 and 52mg/L along with 0.12 mg/L of CuO-NPs, respectively. In this study significant (P<0.05) changes were observed in the antioxidant activity of enzymes and histological alterations in the liver and intestine of fish in G*, G1 and G2 groups while a good ameliorative response of Trigonella foenum-graecum was observed in G3. Dose dependent alterations in glutathione, lipid peroxides, catalase, and malondialdehyde as well as histological architecture of liver and intestine were observed in treated groups, where more alterations were observed in positive control and low dose treated groups of Trigonella foenum-graecum. Moreover, more ameliorative effect was observed in high dose of Trigonella foenum-graecum treated group (G3). This study is novel as no previous data is available on the amelioration of Trigonella foenum-graecum extract against CuO-NPs induced toxicity in fish.

RESUMEN

The efficacy of Allium sativum and Cannabis sativa against Rhipicephalus microplus ticks was evaluated using the adult immersion and the larval packet test. In addition, an in silico approach was utilized by performing a docking study in order to identify the active ingredients from both plants. Results showed a comparatively high lethal effect of A. sativum and C. sativa on egg laying (index of egg laying = 0.26 and 0.24, respectively), egg hatching (33.5 and 37.1, respectively), and total larval mortality (100%, both), at 40 mg/mL. When applied to cattle which had been inoculated with larvae ticks, it was observed that a 45% solution of both herbal extracts significantly reduced the number of ticks by 96 h post treatment. We analyzed in silico 27 known active molecules from both plants and identified in the PubChem database to explore the hypothesis that the effect found on ticks was based on inhibition of acetylcholinesterase (AChE). Vitamin E and cannabidiol are the most potent AChE inhibitors with docking scores of -15.85 and -14.38, respectively. Based on these findings, we conclude that A. sativum and C. sativa may potentially be used for the control of R. microplus, and should be further investigated as a potential supplement to or replacement of synthetic acaricides.

RESUMEN

To determine the prevalence of prenatal depression and explore its association with socio-demographic risk factors, stressful life events and women autonomy/decision-making. The recognition of these problems would play a substantial role in the strategic development of interventions for those Pakistani women who have been suffering from prenatal depression. Analytical cross-sectional study conducted in Allied hospital Faisalabad during a period of 18 months (1st Jan 2019 to 30 June 2020). Data was collected by using simple random sampling technique. EPDS was used to measure prenatal depression. A modified kuppuswamy scale, Life Events and Difficulties Schedule (LEDS) and women autonomy/decision making scale was used to assess the risk factors. A total of 380 women were included in the study. The mean age (in years) ± SD was 29.37±5.27. According to cut-off score >10 on Edinburg postnatal depression scale the prevalence of depression was found as 51.6%. The findings revealed that women education, socio-economic class, BMI, pregnancy duration, history of miscarriage, contraception, stressful life events and women autonomy had significant association with prenatal depression (P<0.05). Socio-demographic factors, stressful life events in previous life and women autonomy are significant predictors of prenatal depression that need to be addressed in order to sustain safe motherhood.

RESUMEN

Obesity is a common disease of developing countries, including Pakistan. Obesity is a risk factor for many diseases which can be life threatening or making the person unable to perform daily routine work. In the current study, clinical trials were designed to evaluate the effects of medical intervention by comparing the effects of placebo control drug "Plasicure" with the herbal medicinal formulation "Obesecure". The test drug formulation was designed on the basis of the screening study for Leptogenic drugs. To evaluate the safety of the test drug, the toxicity index and the safety profile of test formulation was assessed on animal models. The drug was found safe for further clinical study. Randomized Controlled Clinical Trials were conducted. The statistical analysis was carried out by the application of Two-Way Repeated Analysis of Variance test. The clinical findings of randomized controlled trial revealed that the test drug was Leptogenic and effective in weight reduction as compared to control drug Plasicure therapy as the p-value deduced was 0.001 in leptin level and 0.000 in case of BMI after the conduction of Two-Way Repeated Analysis of Variance test. Hence it is concluded that obscure therapy is more significant than control drug Plasicure therapy in the management and treatment of obesity.

RESUMEN

Hyperuricemia is a common metabolic disorder and several herbal formulations are being used for its treatment. The study aimed to develop herbal formulation (Urinil B) and find its hypouricemic effects in vitro and in vivo. Urinil B was prepared by taking Trachyspermum ammi, Piper nigrum and Berberis vulgaris equally. In vitro Dissolution test and xanthine oxidase inhibition assay was performed for checking capsule absorbance and IC50 calculation respectively. For in vivo experimentation, the study comprised of 14 groups of rats (n=6). Results showed that significant xanthine oxidase inhibition was shown by herbal formulation with IC50 of 586±1.5µg/mL. Oral administration of Urinil B 250, 500 and 1000 mg/kg decreased serum and liver uric acid levels of hyperuricemic rats in dose and time dependent manner. 3 day and seven day administration of Urinil B reduced serum and liver uric acid level more significantly as compared to one day administration. However, allopurinol normalized serum and liver uric acid levels in all study groups. The present study indicated marked hypouricemic effects of Urinil B in hyperuricemia induced by potassium oxonate in rats. However, due to caveat of small sample size in this study, clear conclusion regarding hypouricemic potential of Urinil B can't be made.

RESUMEN

The two most important tick species in Pakistan are Rhipicephalus microplus and Hyalomma anatolicum. When associated with cattle, these have one or three host life cycles, respectively, with potential implications for their population genetics and for their vector role in the transmission of pathogens. To compare the two tick species in this context with molecular-phylogenetic methods, during the present study 123 ticks were collected from cattle in northern Pakistan. Two mitochondrial markers of 36 ticks were molecularly analyzed. All 11 R. microplus specimens had identical cox1 haplotypes, whereas the 25 H. anatolicum specimens had nine cox1 haplotypes. The latter belonged to two distinct phylogenetic lineages with high support. However, in the 16S rRNA gene these differences were less evident. Among the 113 ticks molecularly analyzed for tick-borne protozoa, the sequence of Babesia occultans was successfully amplified from two specimens of H. anatolicum. Theileria annulata was present in both R. microplus (10.4%) and H. anatolicum (27.3%), with significantly higher prevalence rate in the latter species. Only one tick, a H. anatolicum female, was positive in the PCR detecting Trypanosoma spp. Sequencing revealed the presence of a new genotype, with the closest phylogenetic relationship to stercorarian trypanosomes (in particular, to a tick-associated Trypanosoma sp. from Japan). In conclusion, the above differences between R. microplus and H. anatolicum may be partly related to their life cycles involving one host or three hosts, respectively. Among the others, host switching (reducing chances of inbreeding) and shorter periods spent on-host (reducing gene flow between cattle herds) are supposed to be important drivers of cox1 gene diversification in case of H. anatolicum as a three host tick species. These results highlight the importance of studying differences in intraspecific genetic diversity and piroplasm burdens between one host and three host ticks in the local scale. In addition, a Trypanosoma sp. molecularly identified in H. anatolicum is reported here for the first time from South Asia, deserving further evaluation concerning its host and vector species.

RESUMEN

Medicinal plants are used by traditional folk healers, modern physicians, and veterinarians as an alternative to conventional drugs to treat a wide range of disorders including parasitic diseases. Some compounds from these plants have been shown to have acaricidal activity and repel arthropods. The cattle tick Rhipicephalus microplus is one of the most destructive pests to the livestock industry in tropical and subtropical parts of the world. The potential to develop herbal acaricides to control R. microplus infestations is critical in maintaining cattle herd productivity, reducing economic losses, and curtailing the overuse of synthetic chemical acaricides. Calotropis procera, the apple of Sodom, and Taraxacum officinale, the common dandelion, were evaluated for acaricidal activity against R. microplus larvae and adults in vitro. Both plant species tested are common indigenous species of Pakistan where R. microplus infestations are widespread across livestock species including cattle, sheep, and goats. Whole-plant extracts derived from C. procera and T. officinale significantly reduced the index of egg laying (P < 0.01) and increased the percent inhibition of oviposition of adult female ticks at a concentration of 40 mg/mL when assessed by the adult immersion test (AIT). Calotropis procera and T. officinale treatments at the same concentration also resulted in larval mortality of 96.0% ± 0.57 and 96.7% ± 0.88, respectively, as measured using the larval packet test (LPT). An increasing range of extract concentrations was tested to determine the LD50 and LD90 for C. procera, 3.21 and 21.15 mg/mL, respectively, and T. officinale, 4.04 and 18.92 mg/mL, respectively. These results indicate that further studies are warranted to determine the relative contribution of individual phytochemicals from whole-plant extracts on acaricidal activity. This information will guide the design of further acaricidal efficacy tests using livestock infested with R. microplus.

RESUMEN

Vulvo-Vaginal Candidiasis is common gynecological disorder. Clinical trials are designed to evaluate the effect of medical intervention with allopathic and herbal medicine to treat vulvo-vaginal candidiasis. The toxicity index and the safety profile of test drug were assessed on animals' model. Toxicity study of polyherbal formulation was done in order to consider it safe before use. In acute toxicity study, a single dose of 2000 mg/kg was given to Swiss Albino mice and in sub-acute toxicity study three different doses were given to Wistar rats. Randomized Controlled Clinical Trials was conducted. Inclusion and exclusion criteria and informed consent from the patients were to be monitored. In acute toxicity study no morbidity and mortality noticed on single administration of dose 2000mg/kg/day. In sub -acute toxicity study no significant changes were observed in consumption of food and water, body weight, hematological parameters, Liver function test, renal function parameters and lipid profile. The statistical analysis showed C. albican was eradicated in 59 participants (78%) out of 75 participants by the use of Candicure (Test drug) and in 56 participants (74%) out of 75 participants by the use of Fluconazole therapy (Control drug). Chi-square test was applied and p-value was calculated 0.3101 which is greater than 0.05 showed that Candicure therapy and Fluconazole therapy is equally significant in eradication of C. albican. The acute and sub-acute toxicity study of polyherbal formulation on experimental animals is safe at a dose of 2000mg/kg/day. The clinical findings of randomized controlled trial revealed that the effect was almost comparable to control drug in eradicating the micro-organism.

RESUMEN

Cough is the common disease condition which affects patients of every age. Numerous OTC medications available in community pharmacies however no antiviral treatment and even antibiotics has been shown to be effective without pre-existing lung infection. The treatment approach of medicinal herbs has been recognized for many decades and even longer for the treatment and prevention of cough. The aim of this study was to evaluate the safety and efficacy of Mukalbion poly herbal chewable tablets for the treatment of cough with improved palatability against a marketed brand (Poly herbal). For the formulation development of test group, the herbs were supplied by the Procurement department of Herbion Pakistan Pvt. Ltd. Althea officinalis (roots), Hedera helix (leaves) and Sisymbrium irio (seeds) were used for the manufacturing of Mukalbion (poly herbal, test group) chewable tablet. The comparative control clinical trial was carried out during a time frame of 07 months with sample size of 70 patients as per epidemiological software for sample size and each group contained 35 (±5) patients. Chewable tablets were administered and evaluated for effectiveness after 15 days of treatment. The data were collected by the patients through clinical trial questionnaire. The validated quality of life questionnaire (LCQ) was also used for assessment. The results were analyzed by applying paired sample T test by using IBM SPSS version 20.00. The p value was <0.005 at 95% confidence interval for cough variables including cough bouts, viscosity of sputum, chest congestion, sore throat and shortness of breath. The LCQ cough scale score was higher in test group as compared to control group. The test group also showed well tolerated in term of palatability. None of the patient claimed any of the side effects and no compliance were observed against the marketed brand.

RESUMEN

Knee osteoarthritis is a common disabling condition that affects a larger number of populations aged above 40 years and this habitually required knee arthroplasty to reinstate leg function, to improve the pain as well as to improve stability. The main objective of this study was to determine the health-related quality of lifestyle before and after total knee arthroplasty. This study was a cross-sectional observational study conducted at Shaukat Khanum Memorial Cancer Hospital & Research Centre, Horizon Hospital and Mayo Hospital, Lahore-Pakistan. In this study, 100 subjects were selected who were scheduled for Total Knee Replacement (TKR) due to advanced stages of knee osteoarthritis. Informed consent was taken from all selected patients. Selected subjects meeting inclusion and exclusion criteria were enrolled for this study. Subjects with any red flag signs or systemic illness were excluded. A baseline measurement was taken by using visual-analog scale (VAS) for pain, the Short Form 36 (SF-36) for health-related quality of life and The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) for disability. Measurements using these scales were repeated after 1, 3 and 6 months after knee arthroplasty. Analysis of variance (ANOVA) test was used to determine statistically significant changes in VAS, SF 36 and WOMAC Score across 06 months. A significant (p<0.05) improvement in health-related quality of life measured of two subscales of SF 36 (Physical Health Component and Mental Health Component) when before surgery readings were compared with that of after 06 months of surgery. Similarly, there was also significant (p<0.05) reduction in pain measured on VAS as well as reduced WOMAC score before and after 06 months of surgery. It could be concluded that TKA results in the improvementof the quality of life and reduced pain following total knee arthroplasty.

RESUMEN

Prevalence of zoonotic Mycobacterium bovis (bTB) disease in human population is underreported from the North of Pakistan. Here, we report on the proportion of human bTB disease among the overall TB patients, drug resistance pattern of bTB isolates, and knowledge, attitude, and practices (KAP)-based analysis of bTB disease. For this purpose, sputum samples from a total of 300 clinically diagnosed TB patients and 100 randomly selected school children suspected of pulmonary TB were processed by culture as well as polymerase chain reaction (PCR) for isolation, identification, and confirmation of Mycobacterium tuberculosis (mTB) and bTB species. Isolates of bTB were processed for drug susceptibility tests. Data on KAP regarding TB were obtained on a pretested questionnaire. Sputum-based PCR results indicated that 288/300 (96%) were confirmed as mTB, while 12/300 (4%) were found as bTB diseases. Interestingly, none of the school child was declared positive for either mTB or bTB. Notably, 274/300 (91.3%) positively cultured samples were identified as mTB, 13/300 (4.3%) as bTB, while 5/300 (1.7%) as mixed containing both. Importantly, except one, all of the bTB isolates were found resistant to pyrazinamide. Surprisingly, most of the bTB isolates (~70%) were found resistant to a broad range of first- and second-line anti-TB drugs. SplitsTree and recombination analysis indicated no evidence of intergenic recombination. Finally, residence, occupation, presence of animals at home, and sleeping alongside animals were found significantly associated with occurrence of bTB disease. To the best of our knowledge, we report for the first time on the high (4%) burden of bTB disease in human TB patients in Peshawar, Pakistan.

RESUMEN

The highly oriented modern detection techniques provide a precise and definite tool for investigation in natural medicines. Current study directed the standardization of eminent biomarker Vasicine in a natural cough syrup. A highly accurate and precise method of High-performance thin layer chromatography (HPTLC) has been developed to certify the quantity of vasicine inside the syrup. Ethyl acetate, chloroform, ethanol and ammonia (6:3:1: 1 v/v) were mobile phase for the study. The TLC plate silica gel G60F254 was used with CAMAG Scanner III and CAMAG Linomate 5. The detected Rf value was 0.51 in both sample and reference standard at 254 nm. International conference of Harmonization (ICH) guidelines were followed for the validation of the developed method. Linearity was achieved in the range of 200µg to 1600µg with co-efficient correlation r2=0.9995. Accuracy was found in between 98.9 to 101.4% however precision was good at both inter and intra-day. As per the standardization of ICH, the developed method was found to be reproducible and showed sharp similar peak with high resolution.

RESUMEN

Toll-like receptors (TLRs) are innate immune receptors that mediate the inflammatory response during HCV infections. The goal of this study was to evaluate the association of TLR9 gene polymorphism (rs5743836) in Pakistani patients infected with genotype 3a of HCV. Total 500 subjects were recruited, 400 HCV patients and 100 healthy individuals. Genotyping of TLR9 (-1237T/C, rs5743836) was carried out in 400 HCV patients (323 interferon responders and 77 interferon non responder) and control group by applying High resolution melting (HRM) curve assay. No remarkable differences in distribution of genotype between HCV (p<0.0001; OR= 3.21, 95% CI= (2.514.12) and control groups (p<0.0001; OR=0.092, 95%CI= (0.0580.14) were observed. In conclusion TLR9-1237T/C gene polymorphism may not be considered as a molecular risk for patients with HCV in Pakistan.

RESUMEN

Tuberculosis is a global health problem, and its early diagnosis is the ultimate strategy for prevention and control. The current study was undertaken to evaluate conventional and molecular diagnostic assays for the detection of mycobacteria in pulmonary tuberculosis (TB) patients from Khyber Pakhtunkhwa region of Pakistan. A total of 259 clinically suspected patients of TB were processed for Zeihl Neelsen (ZN) microscopy, BACTEC MGIT liquid culture and GeneXpert assay. Among 259 samples, 28 (10.81%) were positive for acid fast bacilli (AFB) on ZN microscopy. In liquid culture, the growth of mycobacterium species was obtained in 36 (13.89%) samples while the GeneXpert assay detected Mycobacterium tuberculosis (MTB) in 49 (18.91%) samples. Detection rate of MTB was significantly high (n = 49, p < 0.0095) on GeneXpert as compared to microscopy (n = 28); however no significant difference (p = 0.1230) was observed on GeneXpert (n = 49) and culture (n = 36) based detection of MTB. The strength of agreement between GeneXpert and microscopy was also poor (Kappa value < 0.114, 95% CI: -0.72 - 0.301) which support our results. MTB detection rate among female was high as compared to male TB patients while in age wise, the age group 55-64 years has almost high detection rate on microscopy, culture and GeneXpert assay. Findings of the present study highlighted that GeneXpert is more efficient tool for timely diagnosis and proper TB control in high TB endemic area.

RESUMEN

Elaeagnus angustifolia was analyzed for determination of metals, phytoconstituents, bactericidal, fungicidal and insecticidal effects and to explore its chemical and biological potential. The root, branches, leaves, stem bark and root bark parts of E. angustifolia were found to contain iron, lead, copper, cadmium, zinc, chromium, nickel and cobalt in different concentrations. Crude extract of Elaeagnus angustifolia (Ea.Cr) was tested positive for the presence of alkaloids, flavonoids, saponins and tannins. Ea.Cr and its fractions, n-hexane (Ea.Hex), ethyl acetate (Ea.EtAc) and aqueous (Ea.Aq) showed bactericidal activity against Escherichia coli and Staphylococcus aureus, while against Pseudomonas aeruginosa only Ea.Hex and Ea.EtAc were effective. When tested for antifungal effect, Ea.Cr exhibited fungicidal action against Aspergillus fumagatus, Ea.EtAc and Ea.Aq against Aspergillus flavis and Ea.EtAc against Aspergillus niger. Ea.Hex was active against all three fungal strains. The chloroform fraction (Ea.CHCl3) was found inactive against the used microbes. Ea.Cr, Ea.Hex, Ea.CHCl3, Ea.EtAc and Ea.Aq caused mortality of Tribolium castaneum and Ephestia cautella insects observed after 24 and 48 h of treatment. These data indicate that E. angustifolia exhibits different heavy metals and compound groups. Methanolic extract of E. angustifolia and its various fractions possess antibacterial, antifungal and insecticidal activities, which elucidate medicinal application of the plant.

RESUMEN

The wide spread reason of anemia is Iron deficiency in Pakistan and even worldwide. A clinical trial was undertaken to assess the efficacy of Irocbin formulation for the treatment of iron deficiency anemia as compared to Sherbat Faulad. The curative evaluations of these medicines were recorded in clinically and biochemically identified cases of iron deficiency anemia. The therapeutic evaluation of the different drugs both test and control drug were conducted on the bases of improvement in the subjective signs and symptoms, clinical observations and biochemical investigations at periodic intervals during the course of therapy. This data was collected in the period November 2010 to November 2012 and completed the clinical trials. According to the statistical analysis comparison of data recorded by patients concerning to different variables, showed significant results between test and control groups (p<0.05). By applying ANOVA test, the p values for multiple comparisons of the levels of improvement of Hemoglobin after treatment exhibited significant difference as compared Sherbat Faulad and Irocbin. The control drug Sherbat Faulad with only iron component improves Hemoglobin level and the sign and symptoms but associated with side adverse effects.

RESUMEN

The present study was designed to investigate the antihyperglycemic effect of Persea duthieion blood glucose concentration and body weight in alloxan induced diabetic hyperglycemic rabbits. The results illustrated significant antihyperglycemic activity of crude extract with 17.44% and 28.02% amelioration at 25 and 50mg/kg p.o. respectively after 24th day of drug treatment; equally supported by body weight recovery. Upon fractionation, most dominant antihyperglycemic effect was displayed by aqueous fraction with 22.12% and 34.43% effect followed by ethyl acetate fraction with 24.32% and 32.05% effect at 25 and 50mg/kg p.o. respectively after 24th day of drug treatment. The effect on blood glucose was also reflected on body weight of animals. In conclusion, our study documented marked antihyperglycemic activity of extract/fractions of P. duthiei.
